Durable Functions implement long-running workflows in Azure Functions by providing orchestration primitives, state management, and built-in failure handling via the Durable Task Scheduler backend, enabling reliable task orchestration across cloud environments.

Durable Functions compose complex workflows from simple functions with deterministic execution and replay, enabling function chaining, fan-out/fan-in, sub-orchestrations, and durable state management across orchestration steps.

Yes, Durable Functions work with the .NET isolated worker, requiring Durable Task Extensions and access to a Durable Task Scheduler backend configured via host.json and local.settings.json.

Yes, Durable Functions support human-in-the-loop approvals, order processing pipelines, data ingestion, and reliability-critical business workflows by managing durable state across long-running orchestration steps.

Create a .NET isolated worker Azure Functions project, add Durable Task extensions, and wire up host.json and local.settings.json to connect to the Durable Task Scheduler backend for orchestration.

Durable Functions are designed for long-running, stateful processes like order processing and data pipelines; short-lived, stateless functions may not need orchestration primitives or the Durable Task Scheduler backend.
